Do you have a static compiled version for a Raspberry Pi?

trepex

...
I haven't actually built this exact version on raspi, but the previous driver-icarus version did build OK, though its a standard dynamic build, my expertise does not stretch to modifying the makefile for static linking. Its been a while since I originally set up the dependencies for this, so I'm not quite sure exactly what you will need, the build instructions in the original cgminer README are a bit lacking. I'll have a dig around and see if I can find any notes I may have made ... nope, lost in the mists of time, but google did find something http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/install-cgminer seems straightforward enough.

I have it running (ok, not running) on my r-pi. But I only have two Ztex-1.15x. So the bitstream is not working.
Do you have a bitstream for the single (non quad) Ztex-1.15x?

I also have one Ztex-1.15b but this one never did work on the r-pi (is not detected by "lsusb").

Not right now, but I could build one. The ztex website says the Ztex-1.15x is compatible with the Ztex-1.15d bitstream, and there is a version of the bitcoin verilog source available for this so it shouldn't be too difficult (famous last words, I'm not at all convinced the source code actually matches the officially released bitcoin bitstreams, but the 1.15y source did work, after a fashion). I can't test it myself so it will be a blind port, but that hasn't stopped me before

Give me a few days as I've just started on the Cainsmore CM1 port and I want to make some progress on that one first.

I'm getting a lot of orphan blocks.

mined 7 blocks so far today 3 of which or no good. using 0.8.8.8 wallet and the Cgminer 3.3.1 modded for blake.
anyone else?

[mogrith]

On a different subject,

Kramble I got my CM1 today. So I'm getting drivers and stuff so I blindly fail around with stuff I have no idea how to use. (oddly my idea of fun  )

I activated my old GPU setup. A Win 8 installation with HD7870 + HD7850.
Using cgminer I get 1,5GH/s with just the HD7870 and 2,5GH/s with both. No tuning done (besides
memory clockrate to min and a little bit overclocking).

No orphan blocks seen (but can't say for 100% that had been none).

[trepex]

Idea for a client improvement:

Output the 'newmint' => 'xx' value with the "getinfo" RPC call.
I saw that in other implementations and I did really like it!

[trepex]

Maybe a stupid question, but why do those numbers differ?

cgminer reports: Network diff set to 324K
getinfo (performed against the wallet): 'difficulty' => '1264.37669219',     1:256

In the past I did observe

cgminer: Network diff set to 546K
getinfo: 'difficulty' => '2133.63558956',     1:256

So there seems to be a constant of 256 involved.  network diff / getinfo diff = 256

[kramble]

So there seems to be a constant of 256 involved.  network diff / getinfo diff = 256

There was a change in the way difficulty is reported in one of the early patch releases. The original client/wallet used a difficulty base of 2^24 (compare bitcoin at 2^32 and litecoin at 2^16). This was changed to 2^32 by the patch release (just cosmetic really, but under the old system we'd be approaching a diff of 1 Million which just looked nasty IMHO). Possibly the cgminer version you have is reporting on the old difficulty scale. As long as your blocks are being accepted its not really a problem.

Getting a price fixing for BLC : BTC or BLC : EUR !
I like those experiments!

Yeah it is a graphical issues with the cgminer port from melnikalex the difficulty in the display is shifted too many and thus is out by a multiple of 256

not sure about the newmint feature which wallet was this for and why is it useful?

also worth looking at this exchange they added BLC but not sure about any trust issues as I have never traded on that platform as it is new?
https://openex.pw/

I am going to hold all my coin for now as Blakecoin is based on long term rewards and not just short term gains, I do feel that many have under valued the price but time will tell  

not had much spare time this week as I have been working on the kickstarter for the first game to use Blakecoin as an exchangeable currency for game world credits and mine while you play MMO platform that me and another developer are working on, I did also look into using Blakecoin as the main currency for the game but it would require a major rewrite and has some security concerns but it is a possible stretch goal  

I was also trying to get some more help with the pool software, fixed the submit bug but found a few bigger bugs in the work generation that is resulting in invalid nonce being generated by the miners on the pool

can you post your function for merkleroot calculation?

im finished on my pool code almost. it just needs db functions adding inside for auth and saving shares and im ready, ill give u guys the code when im done (doesnt support stratum im afraid)

I will put stratum-mining-blakecoin code on Github this weekend but it is highly experimental and not fully functional also it imports stratum which might also have bugs that have not been found yet!

the merkleroot calculation is not done in one place in the stratum pool software but try this:

Code:

class MerkleTree:
    def __init__(self, data, detailed=False):
        self.data = data
        self.recalculate(detailed)
        self._hash_steps = None
    
    def recalculate(self, detailed=False):
        L = self.data
        steps = []
        if detailed:
            detail = []
            PreL = []
            StartL = 0
        else:
            detail = None
            PreL = [None]
            StartL = 2
        Ll = len(L)
        if detailed or Ll > 1:
            while True:
                if detailed:
                    detail += L
                if Ll == 1:
                    break
                steps.append(L[1])
                if Ll % 2:
                    L += [L[-1]]
                L = PreL + [doublesha(L[i] + L[i + 1]) for i in range(StartL, Ll, 2)]
                Ll = len(L)
        self._steps = steps
        self.detail = detail
    
    def hash_steps(self):
        if self._hash_steps == None:
            self._hash_steps = doublesha(''.join(self._steps))
        return self._hash_steps
        
    def withFirst(self, f):
        steps = self._steps
        for s in steps:
            f = BLAKE(256).digest(f + s)
        return f
    
    def merkleRoot(self):
        return self.withFirst(self.data[0])

this should be Blake-256(SHA-256(SHA-256(merkleRoot))) as it is in the wallet code?

if you have it finding blocks then its better than my results so far 

[mogrith]

https://openex.pw/  had
Certificate errors, about us is empty, most last trades were for under 1 coin.

Seems legit 

Post if you actually used the site

Actually feel better about that.  Site is in alpha with test data, certs not yet ready and so on.  may make a test account and try it over the weekend

the board I sent kramble has the hashvoodoo project on the controller and the fpga's you might want to play with that
https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner

are you using the xilinx usb programmer and loading the bitstream via the jtag ports?
